For these two, if it's a tossup I'd go with Dinan. If for no other reason than if you run into trouble - while not covered by same warranty - you could at least go to a BMW / Dinan shop and have a single person try to help you. I am just guessing but I have a feeling if the shit were about to hit the fan BMW would be more forgiving with Dinan vs other brands that they have no relationship with.
